' Specification of Letters Patent.

Application' fuea september 1i, 1912. serial No. 719,827.

T0 all whom it may concern:

Beit known that I, RICHARD WEBB BUP.- NETT, a' citizen of the United States of America, residing at the city of Montreal, in the Province' ofQuebec and Dominion of Canada, hafe invented certain new and useful Improvements in Dump-Cars; and I do hereby declare that the following is a full,

clear, and'exact description thereof.

My invention relates particularly to' dump cars of the type disclosed in my United States patent application Serial No. 655253, filed October 17th, 1911.

My invention consists of the combination with ahopper for a railway car having a door adapted-to close to a position in an approximately vertical plane, of a hinge comprising a pair of hinge members one of which is of tubular form and carried by the door, and the other of open tubular'form carried by the hopper floor and adapted to receive and retain the tubular member in hinging relation, the side walls ofthe hopper being furnished with trunnions .adapted toxengage the ends of the tubular vmember of the hinge.

For full comprehension, however, of my invention reference mustl be hadto the accompanying drawings forming a part of this specification in which similar reference characters indicate .the same parts, and

wherein Figure 1 is a vertical sectional view of a dump car hopper taken on a line extending transversely relatively to the car; Fig. 2`is a sectional view 'taken on line A A Fig. 1 of on of the flanged ends of the door and the gobket in thehopper wall engaged thereby; ig. 3 is an enlarged detail transverse sectional view of the hinge With-the door open; F'I 4 is an, elevation of a hopper with the d r closed and illustrating a portion of the car to which the hopper is attached; Fig. 5 is a detail elevation of a portion of the door arid door clamping means illustrating the means for locking the clamping means; Fig.

6 is a detail erspective view of the clamp,` ing device; ig. 7 is a detail perspective view of one of the trunnions for supporting the hinge and illustrating a portion of the hopper wall; Fig. 8 is a detail sectional view illustrating particularly the means for supporting the ends of the hinge plate on the door.

The hopper floor is indicated at b and the ends at c,the floor extending from the center sill d to within close proximity of the vertical plane of thel side sill e, `thus placing the discharge opening approxig mately perpendicularly. Thedump door f is hinged to the lower edge ofthe, floor member and'engages pockets in the side edge g of the ends anda flange upon the` side sill, and it is clamped in its shut position, after having been manually closed, vby

aq'rpclcshaft ov carrying a series of dogs j. t' 'l'his type of door forms an extension of the floor of the hopper and throws the lading ar considerable distance laterally, which is an adalfantage in that it is thrown clearv ofthe rai s. I

W ith doors of this type and applied the manner described to hoppers through" nhich granular commodities are discharged,

while the free edges are effectively closed against leakage by the clamping ap liance described the hinged edge has been-li fore a source of trouble owing to leakage due to wear, imperfect fitting, and, 'in some cases, inherent Weakness unlessvcon'structed from extra heavy materials. In order to overcome these defects the hin e'isfo'rlne'd from a pair of plates m and n riveted to the door and floor member respectively, the free edge of the plate m beingbenttoclosed tubular form lc and the free edgeof the plate n to open tubular form t and adapted to receive the closed tubular member. The hinge and through'it4 the door is supported at its ends and braced by a pair oftrunnions 2- projecting from plates or brackets rfastened upon the end plate ofthe hopper and entering the ends of the tubular' member. w Y

The pockets in the side edges of the hopper ends are formed by riveting olfset plates g to the hopper ends, and the ends of the door are flanged as at g' to enter these pockets. I

The open tubular form hinge member is formed with a series of slots a for the escape of dust, cinders and small particles of lading that might accumulate between the hingemembers and tend to spread them.

A hinge of the form described effectively prevents leakage between the door and hoperetoper floor member, and is strong and durable from one of. said sills`to withinclose proximity of the vertical plane of the other of said sills,4 a-door for closing the opening inclosedby the end. plates, the floor and the lust mentioned side sill, and a hinge joining the door and the floor member and consisting of e member of closed tubular cross section within a member of open tubular cross section. l

2. In e hopper' for dump curs, .end plates, I

hopper sills -nt the opposite Isides of thetop thereof, an inclined floor member extending from one of said sills to within close proximity of the vertical plane of the other of said-sills, :i door for closing the opening inclosed by the end plates, the floor and the last mentioned side sill, and a hinge joining the door and the floor member und consisting of a member of closed tubular cross section within zr member of open tubular cross section, means securing the member of `closed tubular cross-section to the door and means securingthe member of open tubular cross-section to theI floor member.

3. In a hopper for dump ears, end plates` hopper sills at the opposite sides of the top thereof, an inclined Hoor member extending from one of said sills to Within close proximity of the vertical plane of the other of said sills, a door for closing the openin inclosed by the end plates, thefloor an the last mentioned side sill, and e hinge joining the door and the floor member, and consist ing o f'a' member of closed tubular Cross sechopper sills at the opposite sides of the top thereof, an inclined floor member extendnig from one of said sills to within close "proximity of the vertical plane ofthe other off seid sills, a door for closing the opening inclosed by the end plates, the floor and the last mentioned side sill, and a hinge joining the door and the floor member `and consisting of a. member of, closed tubular cross section within a member of open tubular cross section, means securing the inember of closed tubular cross-section .to the door, means securing the member of open tubular cross-section to the floorimember, and means secured to the said end' plates for supporting the said hinge members, said means consisting Aof, a pair of trunnions engaging the ends of the inner hinge member. In testimony whereof I have signedwmy neme to this specification in the presence of two witnesses. l v
